FUNCTIONS
The light comes on any time a card fails to
feed correctly from the input hopper, whether
in response to a punch instruction or to actuation
of MANUAL CYCLE. The punch st0ps, and the
RESET light comes on.
When the DATA ALERT light comes on alone,
this means the logic detected a Transfer Timing
Alert or a Transmission Parity Alert.
When' the PUNCH ALERT light comes on alone,
this means a Punch Alert occurred on the last
card of the program but that the alert status
has not yet been transmitted.
Both portions
onmeans that if aPunch Alert only has occurred
the alert status has been transmitted.
Whether these
alerts halt punching depends
on the program.
HOPPER ALERT portion on means the input
hopper is empty or the output stacker is too
full.
CHAD BOX ALERT portion on means the chad
box is too full or the box is not in its correct
position.
When either light glows, the RESET light also
glows blue and the card punch halts. When the
alert condition is corrected and OPERATE/
RESET is actuated, these lights go off.
Pressing this control in the Halt mode causes
all cards in the six stations of the card track to
be ejected to the output stacker. No cards are
fed in from the hopper. Before this control is
operable, RESET must be on.
